Amphibians Class Game

Defining Characteristics of Amphibians

1. Fundamental Biological Attributes

Amphibians possess unique physiological characteristics that distinguish them from other vertebrate classes:

Core Amphibian Traits

• Dual-Habitat Capability : Ability to live in water and on land
• Permeable Skin : Direct respiratory and moisture absorption
• Metamorphic Life Cycle : Dramatic physical transformation
• Ectothermic Metabolism : External temperature regulation

2. Comprehensive Taxonomic Classification

The amphibian class is divided into three primary orders:

Taxonomic Breakdown

• Anura (Frogs and Toads) : Approximately 7,000 known species
• Caudata (Salamanders and Newts) : Around 700 known species
• Gymnophiona (Caecilians) : Approximately 200 known species

Evolutionary Journey

Prehistoric Origins

Amphibians emerged approximately 370 million years ago , representing a critical evolutionary milestone:
